To all whom 'it may concern:

Be it known that I, ARTHUR H. ScHrLKn,l a citizen of the lUnited States, residing at Vifvilmerding, in the county Of Allegheny and State of Pennsylvania, have invented aA new and useful Combination Burner and Blowpipe, of which the following is a specification.

This invention relates to combination burners and blow pipes, and has for its object to provide such a device which may be used either as a Bunsen burner or as a blow pipe, and which may be adjusted to apply the ame against the object to be heated atV various angles.

A further object of the present invention is to provide such a device of novel and.Y simple construction, and which' shall be convenient and efiicient in use.

To the above and other ends, this invention resides in the combination and construction of parts set forth in the following description and pointed out in the ap- Y pended claims, reference being had to the accompanying drawings wherein the preferred embodiment of the invention is illustrated, and wherein:

Figure 1 is a side elevation of the combination burner and blow pipe. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional detail taken on' the line 3 3 of F ig. 2, being on an enlarged scale.

Referring in detail to the drawings, wherein similar reference characters indicate similar parts, the numeral 5 designates an elbow fixture or bracket which is adapted tobe secured or attached to a wall or other support, and which has a hose nipple 6 connected to the depending arm thereof, and a valve 7 'connected to the other` arm thereof, which arm projects horizontally from the wall or support (not shown) to which t-he elbow is secured or attached. An upright coupling 8 is swi-veled in the end of the valve 7 to rotate or swing about a vertical axis, and carries a tubular arm 9, which arm is arranged. horizontally and is adaptl and is provided with an inturned lip 14 engaging over an outwardly projecting flange 15 provided at the extremity of the tubular arm 9, thereby swiveling the body 10 upon thevfree end of the said arm 9. The other -arm of the body 10, designated by the nuend mounted on the reduced arm 11 and 'abutting against the shoulder 27, the free j end of the mixing tube 24 beingl contracted {as designated by the numeral 25. This mixing tube is also provided with diametrically opposed apertures or inlets 26 and the body 10 hasI an L-shaped duct 16 with its extremities extending to the extremities of the arms 11 and 12, the respective arms 18 and'17 of the said duct passing through the arms 11 and 12 of the body 10. The extremity of the said duct in the arm 11 is arranged adjacent the side ofthe said arm 11 and is counterbored to form a socket 19. A mouthpiece`20 fits in the socket 19 and has an aperture or oriiice 32 extending therethrough. 'The body 10 also has an air duct 28 extending from the extremity of4 y providethe respective sockets 21 and 29. A

small air tube 22 has one end fitting in the lsocket 21 and extends longitudinally within the mixing tube along one side thereof and` has its free end 23 offset and terminating concentrically within the contracted end 25 of the mixing tube. A nipple 30 has 'a stem communicates with the duct 28.

I In use, the nipple 6 is connected with ra supply of gas by means of-a hose or the like, and upon the valve 7 being opened, the gas will pass into the tubular arm 9 and through the duct 16 in the body 10, to emit through the aperture 32 and pass into the mixing tube 24. Air will be drawn through the 'apertures or inlets 26 which will mingle or mix with the gas, the mixture passing through the outer end of the mixing tube24 to produce the regular Bunsen flame. VThe '-mixingmtube' 24 being mounted on the( arm 11 of t-he body 10, which body is swiveled on the end of the tubular arm 9, may be swung or rotated in a lateral plane to apply the Bunsen flame to the object to be heated at various angles, as may be desired or necessary. Air may be forced through the tube 22, by connecting the nipple 30 with a bellows, compressed air reservoir, or the '31 screw-threaded into the socket 2,9y and like, or by connect-ing one end of a short piece of hose or tubing-- (not shown) to the nipple 30 and by placing the other end thereof in the mouth, in which event the operator may cause a blast of air to pass through the said tube. Then air is forced through the tube E20, the same is ejected in a thin or fine stream to draw the burning-- gas into a needle pointed viame, wherebyi the needle pointed flame may be applied against the objectito 4be heated,l for use in fusing, soldering, or :tor otherpurposes for which blow pipes are useful'.

from the object being heated,or-may be swung upon the said arm' againstthe wallV orsupport to which the bracket or fixture 5 is secured, thereby swinging 'the burner? out of=the way. Flames ot various sizes and! used either as a Bunsen burneror as a blowpipe, and maybe-'readily adjusted to apply the-dame atvarious angles with the object to be heated, this device being simple=in its construction, as wellas convenient and effilcient in use;v

Having described the invention, what-is claimed as new is:
